Hi,
In regards to DSL pipeline what is the best way to pass data between stages?
Currently there are some hack's using the env object to access data globally. I don't like this since I've seen numerous bugs related to the implicit .toString() when setting env. There also seems to be a difference between env and environment{} and mutability.
The documents say shared libs /vars/.groovy scripts are global variables... but they look like global methods to me. I can't define anything outside of the method blocks. When I think of a global variable, a method isn't it. I'm looking for a way to persist data across stages.
I haven't tried using /src/.groovy classes much. I've seen an example of a @Singleton groovy class on SO, but I couldn't get this to work. I haven't had much luck in general with groovy classes and DSL pipelines. this becomes the same problem, i want to persist a class object across many stages, but where do I store the reference? Outside the pipeline{} block? Then pass the object into every DSL method?
I have many different DSL pipelines for many different programs these all import 1 common devops lib and one project specific lib. Shared libraries are only using the /vars/.groovy currently and the pipelines make heavy use of the script{} blocks to access functions in the /vars/.groovy. Im pretty sure we're not using /vars/.groovy as it was intended but... it works.
Any pointer would be great!.
Thanks.
